Prevalent Phenomenon of Predation Observed Among Wild Chimpanzees of the Mehale Mountains

Abstract

Abstract I was engaged in the sociological and ecological study of wild chimpanzees in the Mahale Mountains in Western Tanzania for about two years from September, 1975 through October, 1977. It was made clear by the data I obtained concerning carnivorous behavior among wild chimpanzees that their predation happens intensively during only one or two months. It can be presumed that this intensity is distinct from seasonal periods of predation. Also coincidence of time of intensive predation was observed among neighboring group of wild chimpanzees.
